Cyn - Before

  • cyn - before   ( conjunctions / cysyllteiriau  )

    sample sentences:

    Mae'n rhaid i ni achub y ci cyn i'r llifogydd gyrraedd . Dydy hi ddim yn nofio ’n dda .  

    We have to get the dog before the floods arrive. She doesn't swim well.

    Time Conjunctions

    Conjunctions are linking words e.g. and , but , because , or.

    They are used to connect clauses or sentences to form more complex sentences. e.g. 'I want to go out tomorrow but it is going to rain all day.'

    The words - before, after, when, as, while, until, since - are conjunctions. Because they indicate when things happen they are called time conjunctions or conjunctions of time .

    Many time conjunctions in Welsh use a particular construction to join the conjunction to what comes after.

    i + subject + Verb Noun* (mutated)

    In the example below:

    Mae'n rhaid i ni achub y ci cyn i (+ subject) 'r llifogydd (+ mutated verb noun) gyrraedd .

    It should be noted that when the subject is the same in the clauses before and after the conjunction, the 'i' construction is dropped. The rule applies in the above example because the subject of the first clause is 'we' and 'the floods' are the subject of the second.

    * The term verb noun is used here to refer to the basic form of a Welsh verb and is the form usually listed in the dictionary.

    Time Conjunctions Taking The 'i' Form

    ar ôl  - after     

    cyn - before

    wrth - while , as

    erbyn - by (the time) 

    nes - until

    ers - since

    wedi - after

    mutant.jpg In the sample sentence above on this page you will observe that the spelling of two words ( gyrraedd , dda ) differ from the spelling on the relevant Geiriadur listing page ( Cyrraedd - To Arrive , Da - Good ). Be not alarmed!

    This happens because:-

    "Welsh, as with all other Celtic languages, often sees changes made to the beginning of words depending on the word that precedes it, or the role it plays in the sentence. These changes are known as "mutations", of which Welsh has three distinct types. Common situations in which a mutation may occur are when a word follows a preposition, possessive, or number."

    The three types of mutation are:-

    Soft Mutation

    Nasal Mutation

    Aspirate Mutation

    The three links above will take you to further information about these commonly occurring mutations.

    Most Welsh courses and teachers advise students not to worry too much about this at the outset. Fluent speakers will understand you if you forget to mutate a letter. With practice this will come naturally and there is perhaps, no need for beginning learners to make a conscious effort to apply these rules.

    However, if you wish to acquaint yourself with the rules early on you could look out for the 'Mutant Alert' notice on the vocabulary pages and use these as an opportunity to refresh your knowledge by checking the above links.
